With equations like these, the most important thing you want to do is get x by itself.
5x + 3 = 2x + 11 First, you can subtract 3 from both sides of the equation. Since you subtract 3 from the 5x+3 side, that only leaves you with 5x because 3 - 3 = 0. While on the 2x+11 side, -3 means you combine it with 11 (because you need to combine like terms).
5x = 2x + 8 Then you need to do the same thing with the x with coefficients by subtracting 2x from both sides.
3x = 18 Lastly, (remember you want x by itself) divide by 3 on both sides.
x = 8/3
5x+3 = 3x+11 5x-3x = 11-3 2x = 8 x = 4
5x + x - 6x + 2x = 2x
5x+6-2x=-5-x 3x+6=-5-x 4x=-11 x=11/-4
5x+18 = 2x+9 5x-2x = 9-18 3x = -9 x = -3 and y = 3
-5x+3(x+8)=16-2x
How do you add 2x plus 3y equals 18 in 5x-y equals 11
What is the answer to 2x - 5x plus 6.3 equals -14.4?
5x+3 = 3x+11 5x-3x = 11-3 2x = 8 x = 4
5x + x - 6x + 2x = 2x
8x-7 plus 2x equals 6 plus 5x plus 2?
2x+3x = 5x
33
5x+6-2x=-5-x 3x+6=-5-x 4x=-11 x=11/-4
6 + 2x = 5x + 9 , 6 - 9 = 5x - 2x , -3 = 3x , x = -1
5x+18 = 2x+9 5x-2x = 9-18 3x = -9 x = -3 and y = 3
-5x+3(x+8)=16-2x
3x + 5x = 2x + 28x = 2x + 26x = 2x = (2/6) = 1/3
